IMPROVEMENT IN 'ruMBLER-wAsHERs.

Specification forming part of Letters Patent No. 174,090, dated February29, 1876 application filed January 4, 1876.

To all whom it may concern Be it known that I, ALVIN D. PUEFER, Jr., ofBoston, Suffolk county, Massachusetts,

-have invented certain Improvements in Tum'- lieu of upon the tumber, asheretofore, by

which means I obtain al greatly4 increased power, with a decreasedconsumption of water.

My invention consists, secondly, in the employment of an upright spindleto which the motive-power is applied to rotate it 5 this spindlesupporting the tumbler and resting at bottom upon a yielding or elasticstep attached to the valve which controls the ingress of water, thewhole being so arranged that the weight of the tumbler opens the saidvalve and water is admitted to rotate the tumbler and supply the meansof olea-using the latter, while upon removing the tumbler after it iscleansed the valve automatically closes and the Water is entirely shutott', thus avoiding vmuch waste.

Minor features of my invention will be duly explained.

The drawings accompanying this specilcation and illustrating myinvention represent in Figure l a side elevation, and in Fig. 2 avertical section, and Fig. 3 a horizontal section of a portion ot' atumbler-washing appa ratus embodying my invention.

In these drawings, A represents a tubular standard, which constitutesone of a number of similar size and character, which are com` bined witha suitable basin to produce an apparatus for washing tumblers, the lowerend of the standard A being connected with a lsuitable water-supplyunder pressure.

Attached to the lower part ot' the standard A, and connecting with itsinterior, is a pipe, B, which rises upward in a curved or spiral pathand terminates at` top in a nozale, C, so

Y disposed with respect to the standard and to a tumbler applied to thelatter als to direct downward upon such tumbler a stream of water bywhich the exterior oi' the tumbler is cleansed.

Toward its upper part thestandard A is enlarged and forms a globularchamber, D, to receive the motor E, such motor consisting of two or morehorizontal arms F F, which radi= ate from an upright tubular spindle G,such spindle being disposed centrally within the standard A, and beingsteadied by a guide or shelf, a, which constitutes the bottom of thechamber D, and by the extreme upper end of the standard A. A

The upper end of the spindle G receives a disk, H, uponwhich the tumblerrests, while the lower end of such spindle is reduced to a pivot,`b,which rests and rotates upon a step, o, making part of an upright stemor rod d, which is disposed within the lower'part of the standard A, andsteadied at its upper end in a guide, e, which spans the interior ofsuch standard.

The lower end of the stem d passes through an oritlce,f, created in atight shelf', g, which closes the lower part of the standard A, andimmediately below this shelf the stem terminates in-a valve, It, whichoperates in connection with a valveseat, t', that surrounds the lowerpart of the orifice f, the said shelf and valve-seat being disposedbelow the mouth'of the pipe B, as shown in the drawing.

A spring,k,surrounds the valve-stem d, and exerts its stress between thesheltl g and a shoulder, l, formed vupon such stem, with such eii'ect aswhen relieved ot' the weight of the tumbler to raise the valve and closethe port or orifice f, and shut oi flow of water to the pipe B and themotor E.

The weight of the tumbler is borne by the spindle G, and, to obviate thefriction upon the latteras much as possible, I reduce its lower end to apoint, or nearly so, as shown at b, and form it, as well as the step c,of hardened steel,to lessen wear as much as possible. The lower part ofthe spindle G and the armsF F are hollow or tubular, and communicatefreely with each other, and the extreme lower end ot' the former ispierced with several holes, m m, 8vo., for admission of water, while inthe extreme end of each arm F, and upon one side, I create one or moreoriices, a, the orifices of one arm being situated on the side oppositethose of the other arm. Furthermore, I create in the Wall of the upperpart of the chamber D several apertures, o o, 85o., by means of whichwater from such chamber may be directed in small streams upon theinterior of the tumbler, to cleanse the latter.

The operation of my invention is as follows, it being understood, as hasbeen before stated, that water under pressure fills the tubular standardor column A, and that thex-alve-porti is closed: A tumbler, shown atp,which is to be washed, is placed bottom upward upon the top ofthe diskor button H, and its weightlowers the spindle G, and consequently thestem d, and op ns the valve-porti; the result of which is that waterflows through the pipe B and is discharged upon the outside of thetumbler, and not only aids'by its momentum in rotating the tumbler byand with the spindle G, but cleanses the exterior of such tumbler. The uater also flows upward into and lls the standard A'below the shelf a,and enters and hows through the tubular portion of the spindle G and thearms F F, and escaping through the ports a fills the chamber D, fromwhence it passes in small'streams through the ports o and' is directedupon the interior of the tumbler, to cleanse the latter.

The resistance which the streams of water issuing from the ports n meetin the body of water within the chamber D has the effect of impartingrotary motion to the spindle G, with power quite sufficient to rotatethe tumbler which is supported upon such spindle. This resistance may,however, be obtained in other ways, as, for instance, the resistancewhich air, admitted to the-chamber D, would offer to the jets of waterissuing from thefports n would be suthcient under some circumstancesyvits weight, are forced upward by the stress of the spring k, and thevalve L closes the porti and shuts off passage of water to the interiorof the, standard A above such valve, thereby effecting a great saving ofwater.

I claim- 1. In a tumbler-washer, the combination,`v

with the water-admission pipe or standard, of atumbler-support rotatedby the direct action of the water admitted to said support from thewater pipe or standard, substantially as shown and set forth. l

2. As a, motor, the spindle G and hollow perforated arms F F wheninclosed in a contracted chamber, whereby great resistance is offered tothe jets of water issuing from such arms, substantially as andforpurposes stated.

3. The combination of the standard A, motor E, spindle G, stem d, andvalve h, and seat i, substantially as herein shown and set forth.

4. The combination of the spindle G and. motor E, the stem d and itsvalve l1. and the seat t', with the tubular standard A and itsperforated chamber D and the pipe B, substantially' as and for purposesstated.
